Hi, Is there any way to tell whether a string represents an integer (e.g., '3', '-17' but not '3.14' or 'asfasfas') Without using a try/except mechanism? is_int('3.14') = False is_int('-7') = True Thanks, Adam ...
I have two integer values a and b, but I need their ratio in floating point. I know that a<b and I want to calculate a/b, so if I use integer division I'll always get 0 with a remainder of a. How can I force c to be a floating point number in Python when: c = a / b ...
I was working with a variable that I had declared as an Integer and discovered that > is not a member of Integer. Here's a simple example: scala> i warning: there were deprecation warnings; re-run with -deprecation for details res28: Integer = 3 scala> i > 3 <console>:6: error: value > is not a member of Integer i > 3 ^...

I have a libpq program that is routinely inserting numbers into a database. These numbers, which I'm expecting to grow quite large, are stored int the uint64_t type. I'm wanting to send the integer to libpq as binary, but Postgres won't be able to tell its unsigned. Is there a way to specify an unsigned integer in Postgres or libpq? ...
What can be a reason for converting an integer to a boolean in this way? bool booleanValue = !!integerValue; instead of just bool booleanValue = integerValue; All I know is that in VC++7 the latter will cause C4800 warning and the former will not. Is there any other difference between the two? ...
I am having issues with pspell when searching for numeric values I end up with a blank white page and a segmentation fault in the server logs: [Fri Aug 21 10:08:43 2009] [notice] child pid 30064 exit signal Segmentation fault (11) When searching for a string everything works as expected.

How do you compile integer data in Postgres by PHP? My integers are string as the following show by var_dump ( $_SESSION ) 'logged_in' => int 1 'user_id' => string '9' (length=1) // should be int 'a_moderator' => string '0' (length=1) // should be int I compile the values by the following code which ...
In c++ you can do: uint8 foo_bar How would we do the same thing in ruby? Any alternatives? This post seems close to it maybe someone can explain? ...

Hi I have got a column in my database which is set to Int. But my data always starts with a 0 so whenever I add a new record, it strips the 0 off and I don't want it to do that incase the first character has to be a 1 at some point. How can I overcome this issue? Is the best way to use VARCHAR any then validate using PHP? Update I...

The shellscript shown below will show a warning if the page takes more than 6 seconds to load. The problem is that the myduration variable is not an integer. How do I convert it to integer? myduration=$(curl http://192.168.50.1/mantisbt/view.php?id=1 -w %{time_total}) > /dev/null ; [[ $myduration -gt 1 ]] && echo "`date +'%y%m%d%H%M%S'`...
I'm trying to produce random integers (uniformly distributed). I found this snippet on an other forum but it works in a very weird way.. srand(time(NULL)); AB=rand() % 10+1; Using this method I get values in a cycle so the value increases with every call until it goes down again. I guess this has something to do with using the ti...
I'm working on a program where I store some data in an integer and process it bitwise. For example, I might receive the number 48, which I will process bit-by-bit. In general the endianness of integers depends on the machine representation of integers, but does Python do anything to guarantee that the ints will always be little-endian?...
As an exercise, I'd like to write a macro which tells me if an integer variable is signed. This is what I have so far and I get the results I expect if I try this on a char variable with gcc -fsigned-char or -funsigned-char. #define ISVARSIGNED(V) (V = -1, (V < 0) ? 1 : 0) Is this portable? Is there a way to do this without destro...
Hi I have a project where I need to store a large number of values. The data is a dataset holding 1024 2Byte Unsigned integer values. Now I store one value at one row together with a timestamp and a unik ID. This data is continously stored based on a time trigger. What I would like to do, is store all 1024 values in one field. So would ...
